The passive and maintenance-free f e ptic sensor cable is the basis for the EN.SURE real time condition monitoring solution, either integrated directly inside an insulated underground cable (for instance FIMT, fibre in metal tube) or mounted externally on the cable jacket or installed in a separate duct close to the power cable.

Modelling Capabilities

Virtually every cable construction available in the market can be modelled:

Transient Calculations

The cable operating temperature very much depends on the load shape applied to the cable. Therefore, cables have different ratings. Since cables installations have thermal inertia, it takes time to heat up the cable and its surroundings.

Why Adding RTTR to Distributed Temperature Sensing?
